backbone-deep-model
Improved support for models with nested attributes.
Allows you to get and set nested attributes with path syntax, e.g. user.type.
Triggers change events for changes on nested attributes.
Usage
To install, include the src/backbone-deep-model.js file in your HTML page, after Backbone and it's dependencies.
Then just have your models extend from Backbone.DeepModel instead of Backbone.Model.
Example code:
//Create models with nested attributes
var model = new Backbone.DeepModel({
id: 123,
user: {
type: 'Spy',
name: {
first: 'Sterling',
last: 'Archer'
}
}
});
//You can bind to change events on nested attributes
model.bind('change:user.name.first', function(model, val) {
console.log(val);
});
//Use set with a path name for nested attributes
//NOTE you must you quotation marks around the key name when using a path
model.set({
'user.name.first': 'Lana',
'user.name.last': 'Kang'
});
//Use get() with path names so you can create getters later
console.log(model.get('user.type')); // 'Spy'
